BARREL-TRU SSING MACHINE.

SPELIEICATION forming part of Letters Patent No. 306,173, dated October7, 1884.

Application filed March 25, 1884. (No model.)

' To all whom if; may concern Be it known that I, THOMAS MURPHY, acitizen of the United States, residing in the city and county of SanFrancisco, in the State of California, have invented certain new anduseful Improvements in Machines for Trussing Kegs and Barrels; and I dohereby declare that the following is a full, clear, and exact description of my said invention and of the manner in which I proceed toproduce, construct, apply. and use the same, the accompanying drawingsbeing referred to by figures and letters.

My invention relates to machinery for trussing kegs and barrels; and itconsists incertain novel construction and combination of parts andmechanism, as hereinafter described and pointed out.

The several points and features comprising my improvements are, first, ahoop-driver of novel form and action; second, an automaticstave-leveling device; thirdly, a centering de vice, and, fourthly,certain novel mechanism constituting a stop-motion. These parts andmechanism are shown in the accompanying drawings in the form of amachine for trussing barrels.

Figure 1 is a front elevation of the machine; Fig. 2, a side elevationtaken from the righthand side of Fig. 1, and with the crank-disk removedfrom the end of its shaft. Figs. 3 and 4 are sectional views of theupper and the lower or the movable and the stationary driver. Fig. 5 isa plan of the driver.

A is the driver having a continuous drivingedge, a, for the head-hoopand a like edge, a, to engage the bilge-hoop. The space between theseedges is equal to the distance to be left between the hoops when driven.The driver is substantially of cylindrical shape, but internally of twodiameters, the difference between which produces the shoulder a,corresponding to the size of the barrel at the head and affording anopening in the top to let the ends of the staves clear the shoulder.This construction gives driving-edges that are practically continuousand bear against the edges of the hoops all round. Two of these driversare employed, and in an upright machine they are placed within guides,one over the other, the lower one, A*, being fixed to the-bottom of theframe, and the other one, A, fixed to a reciprocating cross-head held inslotted guides. Connecting-rods from two cranks on opposite ends of arotating shaft at the bottom of the frame are attached to the outer endsof the cross-head, and constitute the means by which the movable driveris drawn toward the stationary one. i

B is the bed, and B B the sides of the frame, in which are slottedguides b b, to take the cross-head (l.

D is the actuating-shaft held in boxes (1 d, and receiving motion from amotor-shaft at hand through the medium of a belt and pulleys. 0n theends of this shaft are the two cranks, h h, of which one is on agear-wheel, I, and the other on a counterbalanced disk, J. Apulley-shaft, K, is geared into the shaft D by a pinion, as shown, andthe pulley L uponit is connected with it by means of a frictionclutch,M. A shifting mechanism having a foot -lever, N, is provided at thispoint'for stopping and starting the shaft. Thelever is fulcrumed at a,and is connected with the clutch-lever n by a connecting-rod, W. Acounter-weight, p, is attached to the outer end of the foot to throw outthe clutch when the operator removes his foot from the treadle at theother end. By such mechanism the movements of the driver are placedunder complete control of the operator, and can be arrested at anypoint. In connection with this clutch and shifting mechanism is anautomatic stopmotion device, the office of which is to throw off thepower and arrest the movement of the cross-head at the end of eachupward stroke.

This device consists of a spring, B, fixed at one end to the bed-timberof the frame, and having a tooth or notch, 1", on the free end, thatprojects over the end of the foot-lever N, so as to engage with and holdit down. This end of the spring is connected with an arm, 8, on arock-shaft, 8 to the end of which a crank, 25, is fixed. From this cranka long rod, T, extends upward alongside the frame B, and carries anadjustable tappet, T,which projects over the line of movement of thecross-head. The tappet is held by a setscrew, u, and being adjustableupon the rod it can be placed to be struck sooner or later in themovement of the cross-head, as required. The movement of the rod thusproduced turns the rock-shaft and draws back the spring R clear of thefoot-lever, when the weight 1) acts to throw off the clutch. Thecross-head and driver are counterbalanced by a Weight, W, and aconnecting-cord, w, turned over pulleys 10 This permits the cross-headto be arrested and held at any point. In a machine where the drivers areset to work horizontally this counter-balance is not required.

P is an automatic leveling device fixed in the driver to act against theends of the staves, and Q is a centering device that brings the barrelinto line when it is first set into the machine between the drivers.This leveling device is a yielding head, P, set in the open end of thedriver, and confined by a center post, 19, that takes into and moves ina socket in the cross-arms a a of the driver. Short guidepins pprojecting from these arms serve to hold cylindrical springs 12 behindthe head. The centering device is formed of several springs Q, fixed atone end to the driver-body,

.and from this point bending downward and also inward through slots aa", that are out through the sides of the driver. The free ends of thesesprings have a strong curve inward to bring them within the innersurface of the driver, and they also extend below the rim.

As the end of the barrel enters the driver, and before the driving-edgescome down to the hoops, these springs, coming in contact with the edgesof the barrel, bring it into line and accurately center it under thedriver. Bolts H pass through lugs A on the sides of the driver-body andtake into the part to which the driver is fixed. In the movable driverthis part is the cross-head O, and in the fixed one it is ,the bed.Rubber springs V are interposed between the driver and the frame attheir points of fastening, as shown, so that a somewhat yielding orelastic instead of a rigid bearing for the devices is obtained.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

1. In a machine for trussing kegs and barrels, a combined driver andleveler having two ledges for engaging two different hoops, and aleveling device mounted therein consisting of a plate or disk secured tothe driver by means of a screw-bolt and nut, and having elastic materialor springs interposed between said disk and driver, by means of whichthe barrel shall first be leveled by the yielding disk and then have thehoops driven, as set forth.

2. A head for guiding, leveling, andtrussing barrels, consisting of thedriver A, having the two ledges a and a and yielding disk or plate 1?,and the curved spring-guides Q eX- tended out through theopenings in thedriver, and adapted to receive the barrel between them and guide it intothe driver, substantially as set forth.

3. The combination, with the driver-head and means for verticallyreciprocating-the same, of a clutch and its operating mechanism,consisting of a footlever and connections, the spring-catch It), forengaging the foot-1ever, the rock-shaft s, and connections to thespring-catch, the upright rod T, connected to the rock-shaft at thelower end, and provided with the tappet T at or near the top forengagement with the driver-head, operating as a 7 5 stop mechanism,substantially as set forth.
